Add API project registry endpoint
What does this MR do?
Add an API endpoint to get project (Docker) registry information path and tags.
Are there points in the code the reviewer needs to double check?
Maybe "disable" the endpoint if there is no registry setup ?
Why was this MR needed?
Because we need to know what images are in our Docker registry. For now, Gitlab oauth doesnot provide catalog scope, so it's impossible to browse Docker registry /v2/_catalog API :-(
